INTERACTIVITY
If you use the first multimedia application, the content progresses without you having to control the flow of the movie. Your only control is to press the “play” and the “stop” buttons. This interaction is called linear interactivity. On the other hand, the second multimedia application allows you to decide which part you would like to view, or how much you want to know about the content. This interaction is named non-linear interactivity.
WHAT IS INTERACTIVITY?
Interactivity refers to the way users interact with a multimedia application or program. The user can use input devices such as a keyboard, joystick, mouse and touch screen to interact with the application through the computer. Another example is a computer game. It allows the user to use the left and right arrow keys to control the movement of the game.
WHAT IS LINEAR INTERACTIVITY?
In linear interactivity, the user interacts with the multimedia application without controlling the progress of the content.
WHAT IS NON-LINEAR INTERACTIVITY?
Unlike linear interactivity, non-linear interactivity allows the user to interact with the content according to what the user wants from the content. In other words, it is a two-way communication.
EXTENSION : NON-LINEAR INTERACTIVITY AND VIRTUAL REALITY
Virtual Reality is the best example of multimedia technology which uses non-linear interactivity.
